Majorana zero modes are expected to arise in
semiconductor-superconductor hybrid systems, with potential topological
quantum computing applications. One limitation of this approach is the
need for a relatively high external magnetic field that should also
change direction at the nanoscale. This proposal considers devices that
incorporate micromagnets to address this challenge. We perform numerical
simulations of stray magnetic fields from different micromagnet
configurations, which are then…
